The author concludes that commercial-scale output of simulated geological hydrogen is unlikely before the mid-2030s without multi-year pilots and clearer standards. This report maps the emerging field of stimulated geologic hydrogen—engineering the subsurface to make H2 in-situ via methods such as Electrical Reservoir Stimulation (ERS) and Advanced Weathering Enhancement (AWE). Most approaches sit at TRL 2–6 (ERS/AWE most advanced), with […]
